The Importance of Temperature

Ensuring the proper temperature of beverages and across your entire beverage system makes a difference in taste, experience, and profit. Staff may know the ideal temperature for storing wine, keeping kombucha fresh, and serving the perfect beer, but seemingly tiny habits can drastically affect temperature and therefore, your product. Storage temperature can affect beverage foam, carbonation, and flavor, impacting the customer experience and your revenue. As simple as it is for temperature to negatively impact your venue, it’s just as simple to implement processes that can prevent unwanted temperature changes. Read on to learn more about the effects of temperature on beverages and how Sestra’s TapWise technology takes the guesswork out of managing your product temperatures.


Beer foam is a result of a phenomenon known as nucleation. Proteins with a high rate of hydrophobicity form bubbles with the help of CO2 produced in the fermentation process. Thick, compact, and long lasting foam aerates beer’s aroma and affects taste sensations.

Increased temperatures can create too much foam, causing your lines to fill. Foam is 25% beer so when you have to clear your lines, that foam becomes wasted beer, causing your venue to pour revenue down the drain. When you consider the effort involved in ordering, stocking, moving, and connecting each keg, it is important to ensure that every ounce turns into revenue for your venue.

Beverage temperature and foam

These graphs illustrate a venue’s storage temperatures and resulting top offs due to foam. As you can see, at the same time temperature spiked, the venue was topping off 1 in 3 beers, as a result of increased foam. 


As temperatures increase, carbon dioxide separates from your beverage, causing carbonated beverages like prosecco and kombucha to lose their characteristic “fizz”.  This also often results in lost revenue due to the need to replace a drink. “Flat” is a common beverage complaint that can often be avoided by optimizing temperature.

When beer begins to go over 38 degrees, even by as little as half a degree, the CO2 begins to come out of solution and  creates major foaming issues.  


To put it simply, cold beverages stay fresher longer and taste better. While higher temperatures don’t result in a specific taste, they speed up the oxidation process, causing beverages to stale prematurely or enter a second stage of fermentation. Beer, for example, can develop a cardboard-like flavor, lose its hoppiness, and have a degraded aroma. 

Most cold brew coffee becomes bitter and metallic if not kept properly chilled. 

The above issues all impact…

The Customer Experience

What happens when a venue serves beverages that haven’t been stored at the proper temperature? Customers won’t stay customers for long and both your bottom line and your reputation are affected. Prioritizing beverage temperature in storage, in the line, and through dispensing, contributes to the ideal beverage and a positive customer experience. 

5 Ways Your Venue Can Prevent Unwanted Temperature Changes:

1. Train staff to rotate kegs quickly, minimizing the time kegs are between refrigeration

2. Keep walk in doors closed at all times

3. Schedule defrost cycles well outside of service hours


Your refrigerator intentionally turns off to raise the temperature during defrost cycles (pictured above). Scheduling these cycles at least 3 hours before beverage service prevents your inventory from freezing while ensuring beverages are the proper temperature when dispensed.

4. Place light beers furthest from the door as they’re most impacted by high temperature

5. Sign up for Sestra temperature alerts 

TapWise temperature alerts occur in real time, warning staff of potential issues and allowing your venue to solve problems before they happen. You can check your temperature trends to isolate behaviors that are increasing temperatures and affecting your product. In addition to the alerts your venue and staff receive, Sestra’s Pour Center Control monitors customer temperatures on an ongoing basis as a part of our Dispensing as a Service (DaaS) solution.

While seemingly tiny habits can sabotage your inventory, simple changes can optimize storage temperature, resulting in just the right amount of foam, carbonation, and flavor. Not only can TapWise send alerts that help you address problems before they can negatively impact your product and the guest experience, Sestra’s Customer Success team can help your venue analyze data, isolate trends, and update practices.

Save Space with TapWise

Space is a valuable and limited commodity and saving space creates opportunities and benefits that can make a real difference. Save space with TapWise beverage dispensing through self-service, tap layout, inventory management, and more, optimizing your venue for maximum capacity. Not only does TapWise make space for additional guests and minimize excess inventory, those benefits generate additional benefits, including improving your bottom line and reducing waste. Whether you’re interested in monetizing your lobby, optimizing inventory at sea, or satisfying thirsty fans, TapWise beverage dispensing can be your venue’s space saving solution.


Allowing patrons to serve themselves reduces staffing needs, optimizing space for guests while also helping your venue combat the labor shortage. If your venue packs in the patrons, reducing staff means you’re able to maximize the number of paying customers on site while still providing exceptional service. The staff that are on site are then able to fulfill food orders, ensure cleanliness, and heighten the guest experience.

Not only does self-serve through TapWise create space by reducing staff needs, the stations themselves can be built to optimize space at your venue. You can easily integrate beverage technology with your existing hardware or update your technology.

Tap Walls

Sestra tap wall behind the bar

Tap walls can be installed behind the bar for streamlined tended service or without a bar to allow for self-service. Kegs can be stored in cabinets directly below the taps or behind the wall itself.

Tap Walls Behind the Bar

Tap walls behind the bar keep counter space clear, offering a clean look and better staff/guest interactions. And don’t worry about having your back to patrons, touchless and one touch dispensing allow bartenders to serve the perfect pour while engaging with guests.


Self-Serve Tap Walls

Self-serve tap walls offer double the space savings by reducing staff needs and increasing floor room. 

Self Serve Tap Wall

Tap walls aren’t just for restaurants and breweries. The space saving benefits of TapWise also apply to tap walls at event spaces and performing arts centers. Self-serve tap walls in lobbies allow those who want to indulge to fill up their glasses without disrupting the flow of other theater goers. It also allows for more guests to be served during limited intermission times.

While cafeteria style venues can implement self-serve beverage dispensing, tap walls in lobbies and other open areas can utilize Bring Your Own technology to ensure patrons are of drinking age and have paid for their beverages before dispensing.

Mobile Bars

Mobile bars are exactly what they sound like. They’re 4-line, 67” mobile carts with room for up to 2, 20 liter kegs of beer, wine, kombucha, cold brew, or cocktails. Mobile bars can be moved throughout your venue, moved between indoors and out, and increase points of service depending on seasonality, for large events, or year-round. If there is a single exhibit or area of your venue that typically receives more foot traffic, stationing bars throughout opposing areas of your venue can disperse crowds, optimizing your venue’s space.

In addition to their self-serve and space saving capabilities, mobile bars reduce wait times and provide consistent pours. If you’re considering adopting mobile bars at your venue, check out 4 Game Changing Ways Mobile Bars Are Increasing Sales.


The space saving benefits of TapWise beverage dispensing extend beyond the layout of your taps. IoT technology connects dispensing data from taps directly with otherwise siloed data, including Point of Sale data, guest behavior, and loyalty programs. Data can be used to track seasonal changes, the success of specials and promotions, and even daily trends, helping you predict inventory and staff needs. The ability to predict inventory needs ensures you’re not storing more beer, wine, liquor, or cocktails than you actually need, saving space and reducing waste from spoilage.
